AIR BRAKE OF THE 0NE-LINED TYPE Filed July 21. 1926 The chamber-'37 serves for furnishing a certain quantity of air for quickly applying the brake blocks to the wheels, to be braked, and, further for smoothing the braking ac- 'tion throttlingthe air streaming from the auxiliary container to the brake cylinder. F or this purpose a small passage 90 is provided between the aux liary conta ner pipe 66 and the chamber 37, hereas a larger passage 91 is provided between the feed "valve 5' andthe chamber 37, sothat the fill-' 'ing action of the train ished,

pipe is not dimin- I claim: 1 r 1. An air brake of the one lined type, comprising in combination a train pipe, a brake cylinder, an auxiliary container, a distributor for adm ttmg and exhausting air to and from said brake cylinder, a piston like from said brake cylinder, a piston like actingjmember in said distributor and means for loading said member on one side by train pipe pressure and on the other side byaconstant fressure 'reater than atmos heric C) pressure anda second piston like member,

'operatively connected to said first member,

and loaded by the brake cylinder'pressure in opposite direction to the action of said constant pressure. f

3. An air brake of the one lined type, comprisingin combination a train pipe, a brake v cylinder, an auxiliary container, adistributor for admlttmg and exhausting air to and from said brake cylinder, a piston like acting member in said distributor and means for loading said member on one side by train pipe pressure and on the other side by'a co'nand loaded by the brake cylinder pressure in opposite direction to the action of said constant pressure, and a double valve' opei atively connected to said members so asto admit and exhaust air to'and from the space adjoining said second member loaded by the brake cylinder pressure.

4. An air brake of the lined type, comprising in combination a train pipe, a brake cylinder, an auxiliary container, a distributor for admitting and exhausting air to and from said brake cylinder, a piston like acting member in said distributor and means for loading'said member on one side by train pipe pressure and on the other side by a constant pressure, a double valve connected to said members so as to admit and exhaust air to and from the space adjoining said second member loaded by the brake cylinder pres sure, and a second piston like member, .operatively connected to said first member, and loaded by the brake cylinder pressure in opposite direction to the act-ion of said con stant pressure and an air chamber adapted to be connected. through saiddouble valve to the space adjoining said second member loaded by the brake cylinder pressure. v

v 5. An air brake of the one lined type, comprising the parts enumerated in claim l, the said air chamber being connected to said auxiliary container by a smaller passage than to said train pipe. v V
